I have moved to noise cancelling buds.... and listen to music while I shoot. I have found the muffs really interfere with the gun stocks I shoot, when pressing cheek to stock.
I use foam earplugs rated at 34dB. They work really well. I run chainsaws, tree-service chipper, and I like shooting. The only times I've needed to put muffs over my plugs is when somebody else is using a muzzle brake near me.
Even then the blast is unacceptable.
I hate muzzle brakes; throw yours away!
Wouldn't it be great if suppressors were deregulated and encouraged?
